    Line up the sheets of mosaic on the wall so that they match the sheets on the ledge, which will ensure that you get a symmetrical look.

  • Step 9. Cut around small obstructions

    While measuring, take into account any obstructions, like a water outlet, and mark where it lines up on your tile(s). To cut the tile, pull it away from the sheet. Put on your gloves and cut the tile with your tile nippers.

  • Step 10. Measure up the wall

    Using the spirit level, draw a line down from the centre of the ledge.  This will be your reference point to work out how many tiles you need and keep them symmetrical.

  • Step 12. Lay tiles down on the wall

    Working from the centre, place your sheets of tiles onto the adhesive, and place any cut tiles back in their place. 

    Previous Step Next Step
    Apply adhesive with notch trowel

  • Step 13. Cut around large obstructions

    If you come across a large obstruction in the wall, like a mixer tap outlet, you’ll need to cut space in your tiles to accommodate it.  Line your tile sheet up next the outlet and mark it’s position and size on your tile sheet.

    Using the spirit level, transfer your marks into the correct position on the tile sheet and mark them up with your pencil. Then use the angle grinder to cut a hole in the tiles. Make sure that you wear your safety gear.

  • Step 14. Finish laying the tiles

    Lay any cut tiles into place over their obstructions, and continue tiling the rest of the wall. Use the rubber grout trowel to press the tiles down and also check that it’s level before the adhesive dries.

    Once you’ve finished and the tiles are dry, the next thing you need to do is add some grout to complete the look. To find out how, watch our How to Grout Wall Tiles video.
